Watching The Channel Low

Whatever happened to Crazy Snowfan?

Did he put in an appearance this winter?

[Mark Griffin]

Well its just starting to turn sleety here in rugby now.. about time too

[SussexmarkyMark]

Moderate to heavy rain here for the last 10 hours. Temperature rising rapidly in the last hour - now up to 8.2c !

[Severe Siberian icy blast]

The key to snow potential being good in the Midlands and inland southwest tonight is rapidly falling thickness values.

The current run continues to show thickness as high as 546 dm over the snow zone at 18z but by 03z it has fallen to about 531 dm and with the backing wind direction, available cold air source (temp at Leek for example barely above freezing), evaporative cooling, and the nocturnal factor, everything points to a gradual changeover from rain to snow throughout this zone. Amounts could still reach 10-20 cms when the change comes. The change will come later in counties just north and west of London so amounts will be lower there, 3-7 cms perhaps. Some coastal sections of the southeast and south will only see a touch of snow near the end of the precip tomorrow morning.

With the low only arriving now near Cornwall, the whole thing is setting up well for an overnight snowfall event but the process will take 2-3 more hours for most areas that are about to get their snow, thickness will be too high until about 20 or 21h.

There may be an outbreak of thunder in the southeast around then also, as part of the occlusion process, the thickness collapse is fairly rapid. I would think there is fairly high tornadic potential in northern France this evening along the developing cold front which is clearly visible on satellite imagery and radar through western France.

Thanks for that info, i was wondering if the lows only just approaching cornwall , does that mean the ppn will be chucked further north then cause at min it looks to be goin south then origonaly forecast. comments pls??????????????

Now snowing in swinton S64

Could get something of a suprise

[TEITS]

Im not sure who watched the BBC forecast but you will of noticed the risk of snow is further S. This is most certainly in response with the BBC expecting the main core of the heavy precip to be further S. So with this in mind anyone who uses the Met O radar you need to see the intense rainfall move further N. If it remains to the S you are more likely to see rain with W Midlands/Wales being the exception.

I also noticed they removed the risk of snow for E counties tomorrow morning as the LP pulls away and this is definately due to the warming effects of the N sea as the upper temps are actually colder!

[Iceberg]

A very sharp temperature gradient now building 10C in Bournemouth and only 25 miles north in Salisbury it's 3C.

[snowwonder]

Very heavy snow here DP now down to 0.7 and temp 1.0. I think were are in for a dumping!!!

[kold weather]

Yep Iceberg, not really surprising when you see how potent the front is at the moment, pretty tight gradient, I'm just about to enter the milder air it seems as the rain is easing off as the front lifts just to the north so will be interesting to see how the temps respond.

[Hurricane Debby]

3.5 degrees here and wet, wet, wet. Been raining since 7am this morning but nothing really exciting to report. Roads are starting to get pretty flooded mind...I know they have said all the action will be this evening but I'm not so certain and think they have over hyped this...

[k66yla]

Just got off the phone to my mum in SW France(Charente) wind speed is picking up there rapidly now, 160kph due tonight dropping to 100kph tomorrow morning.

[Albion Snowman]

Moderate snow here now. Regarding temps in the South nudging double figures-this was forecast earlier today by the BBC and it shouldnt last long before the colder air digs back in if i remember correctly.

[The PIT]

Strange that there's so little wind about. Just looked on XC weather and nothing of note anywhere. At the moment it's the rain and snow that's the talking point. Maybe the quietest storm ever ????

Also it seems the prec band is pushing further north than expected and being more of snow than thought earlier.

Actually, i was thinking exactly the same. I think the original reason why the MO classed it as a winter storm was the PPN and Wind speeds. Its very still where i am now and has been all day.

Snowing 25 miles to your north as well

[Cheese Rice]

He's been around

Yep the warmest part of the warm sector has arrived over you - illustrated nicely by the NMM tonight (albeit that I think it has the low tracking a little way south of where it actually is):

18:00

20:00

By the early hours it's long gone:

[stewfox]

Snowing 25 miles to your north as well

Snow grains now , very interesting as its clealry shows against my semi horizontal window, the snow then the snow grains
